Title: Semiconductor device and manufacture thereof
Inventor: UENO KATSUNOBU
IPC: H01L29/73
Filed: 1990-08-24
Abstract: PURPOSE:To alleviate a lattice distortion of a hetero boundary and to increase resistance against heat treatment, etc., by incorporating carbon of 3.56Angstrom  of lattice constant in a concentration range of 1X10<16>-1X10<18>/cm<2> in a silicon.germanium layer in hetero junction on a silicon layer. CONSTITUTION:Polycrystalline silicon.germanium layers 6, 7 formed on the periphery of a base layer 9 become base lead electrodes, and connected to electrodes (not shown) through contact holes 14 formed at an SiO2 film 10. Carbon contained in the layer 6 of the layer 9 is the same diamond crystal as that of silicon or germanium, its lattice constant is 3.56Angstrom  to be smaller than that of the germanium, and hence a lattice distortion can be alleviated, and resistance against a heat treatment for causing a slip line is increased. Thus, distortions are scarcely generated at the layers 6, 7. Further, since the carbon is contained in low concentration of 1X10<16>-1X10<18>/cm<2> in the layer 6, its conductivity is not lowered by the mixture of the carbon.

IPC: B41J2/05
Filed: 1983-11-30
Abstract: PURPOSE:To maintain a better liquid drip forming property for a long time by making the thickness near the part contacting at least the heat generating section of at least one pair of opposed electrodes thinner than the other parts of the electrodes. CONSTITUTION:The thin parts of electrodes 213 and 214 are made in the double- layer structure with the upper layer as etching resistant layer and this facilitates the etching to make an electrode formed on the upper layer as specified in the size and shape. Otherwise, in stead of making the thin part of the electrode in the double-layer structure, the thin part and the other part are formed from different kind of material in such a manner that etching resistant material is selected for the thin part and a relatively easy to etch material for the other parts. This facilitates selective etching of the upper layer alone.

Title: Magnetic recording medium
Inventor: KADOKURA HIDEKIMI
IPC: C09D5/23
Filed: 1984-10-25
Abstract: PURPOSE:To obtain an excellent electromagnetic conversion characteristic by having a magnetic layer into which specific inorg. powder and magnetic powder are incorporated. CONSTITUTION:The inorg. powder having <=0.35mum, more preferably 0.1-0.3mum average primary particle size and >=40 deg., more preferably 42-50 deg. angle of repose is used as a reinforcing material. The wear resistance and scratching resistance of a magnetic head are improved but the surface smoothness of a tape is deteriorated and the electromagnetic conversion characteristic is deteriorated if the average primary particle size of the inorg. powder is larger than 0.35mum. The inorg. powder having <=0.1mum average primary particle size is costly and has a slight reinforcing effect. The angle of repose is an extremely important factor and indicates the shape factor of the inorg. powder. The wear resistance and durability of the magnetic layer are deteriorated and the reinforcing effect of the tape is lost if the angle of repose of the inorg. powder is smaller than 40 deg. and therefore the angle of repose below said value is undesirable. The inorg. powder is exemplified by alpha-alumina, etc. having >=5 Mohs hardness.

Abstract: PURPOSE:To easily read out the original point of a bar code added to a continuous body of rotation or a two-dimensional matter and also to facilitate the parity check by putting a 2nd code using a polarizing filter on a 1st code like a bar code, etc. CONSTITUTION:The polarizing filters 12 are added to the codes 11B and 11D of the even rows of a two-dimensional bar code 1 including the bar codes 11A, 11B, 11C and 11D. Thus the signals outputted from the 1st and 2nd photodetecting parts 25 and 26 via an optical scan part 24, the 1st and 2nd mirrors 23 and 22, etc., are confirmed and the output of an exclusive OR circuit 271 set at H respectively during an optical scan. While the signal outputted from the part 25 is confirmed and the signal outputted from the part 26 is not confirmed during the optical scan of both codes 11B and 11D. At the same time, the output of the circuit 271 is set at L. As a result, it is possible to decide that the optical scan direction is not correct if the switching cycle between H and L is discordant with the optical scan cycle. At the same time, an original point of the optical scan is obtained with comparison with the optical scan timing. Therefore the rotary original point signal of a continuous body of rotation can be easily read out and the parity check is also facilitated.

Filed: 1986-09-22
Abstract: PURPOSE:To prevent extremely thin wall thickness from developing at the peripheral end of the bottom part and consequently form uniform wall thickness over the whole region of the bottom part by a method wherein a biaxially stretching blow molding is realized in a form with no reverse curving and, after that, the reverse curving of the central part of the bottom part is realized through the deformating by simple caving-in. CONSTITUTION:By axially stretching a primary molding S1 under the condition that the central part of the bottom part of the molding S1 is softly pinched between the tip of a bottom pin 3 and the tip of a stretching pin 5 and, after that, forcing pressure fluid in the molding S1, a secondary molding S2 is obtained. After the pressure in the molding S2 is brought to near atmospheric pressure by exhausting the pressure fluid forced in the molding S2, the bottom pin 3 is advanced by the desired amount so as to push the central part of the bottom part S2b inwards in order to obtain a tertiary molding S3. The tertiary processed item S3 is released from a mold 1 under the state being held by a holder 4 and uniformly heated by a heater 6 up to a temperature to develop heat shrinkage so as to be deformed through shrinking to a quaternary molding S4. During the state that the temperature of the quaternary molding S4 is still within the stretchable temperature range, the molding S4 is assembled under the state being held by the holder 4 to a secondary blowing mold 2 so as to realize the stretching of the quaternary processed molding S4 to a product S.
